It’s nearly the same breakdown for me except I have a much higher percentage of apps that I should just delete, and the ones I actually use are also the ones I generally demo (such as Instagram, Launch Center, OmniFocus, and Simplenote).
When I first got an iPad back in 2010 it was Safari that I usually used to show off the device — Showing them a familiar thing (a website) in a new context (9.7-inch touch screen device) was the easiest way for people to instantly get a foundation for how awesome the iPad was. Now that most people I encounter are pretty familiar with the iPhone and iPad, if they don’t own one already, they want to see demos of the apps I use on a regular basis.
